The unnamed 'person of interest' leaving the Unno Boutique Hotel in Kissimmee on the day of the fire

Police have identified a possible suspect wanted in connection with a fire that tore through a Disney World hotel and displaced 250 people over the Christmas period.

Using surveillance footage from the ravaged Unno Boutique Hotel in Kissimmee, Florida investigators have released images of a man who was seen leaving the premises on the day of the fire on December 23.

Florida police described a person caught on a surveillance camera at the hotel as a 'person of interest (who) may have valuable information' about the arson investigation although officials have refrained from calling him a suspect outright.

Investigators are now trying to determine where exactly he was when the fire started.

Investigators also revealed that the fire began when someone ignited flammable mattresses piled against the hotel's outside wall.

'Someone had to walk up to them with an ignition device, a lighter, matches, something like that, and light the mattresses on fire,' said Lt. Cynthia Campina, from the Florida Bureau of Fire & Arson Investigations.
